C.39:4.4 - Refine only what can change the answer

Follow a constituent contribution further when its unresolved obtaining way could change the whole’s result, feasibility or burden. State that effect before opening another search. A qualified existing operation can remain intact while one missing connection is developed.

Choose the next level by the decision it enables, not by a fixed decomposition depth. Stop when the explanation is sufficient for that decision. If it is not, name the missing operation or support question and what observation would allow reconsideration.

Compare further inquiry with using the adequate current answer, narrowing the sought result and stopping. Include the effort and displaced work. A technically interesting uncertainty need not be resolved when none of its attainable answers would change the current decision.
